Hi Guys,
I am seeing 1-2% grpc Traffic gets dropped even after following best
practices.
I am using channel polling of size 10-20, best practices suggested in for
polling is we have a unique channel name and even with retry added these
numbers did not change.
For channel creation I using bellow code:
Map<String, Object> customArgs = new HashMap<>();
customArgs.put("channelNumber", String.valueOf(channelNumber));
ManagedChannel channel = ManagedChannelBuilder.forTarget(grpcUrl)
.usePlaintext()
.defaultLoadBalancingPolicy("round_robin")
.enableRetry()
.maxRetryAttempts(6)
.defaultServiceConfig(customArgs)
.build();
And the Error msg I am getting is:
RankingServiceSort EXCEPTION : UNAVAILABLE:
unavailableio.grpc.stub.ClientCalls|toStatusRuntimeException|262
io.grpc.stub.ClientCalls|getUnchecked|243
io.grpc.stub.ClientCalls|blockingUnaryCall|156
proto.RankingServiceGrpc$RankingServiceBlockingStub|sortInventoryData|169
RankingService.RankingGrpcConnector|GetInventoryRanking|80
Please help us we are stuck here from 3-4 months, We are using aws grpc
supported ALB in between and these best practices though helped us in
reducing DeadLine Acceded issue but service Unavailable cases are not
getting reduced. Did now found any detailed documentation as well. We are
having 2 instances for this service and both CPU and memory and network
bandwidth is not at exhausted, used bellow 5%.
Thanks & Regards,
Pawan Sharma
